JOHN V. OARVELL, OF EDDYVILLE, ILLINOIS, ASSIGNOR OF ONE-HALF TO JOE W. KING, OF WASHINGTON, DISTRICT OF COLUMBIA.

KEYHOLE GUARD FOR PADLOCKS.

SPECIFICATION forming part of Letters Patent No. 483,345, dated September 2'7, 1892.

Application filed October 6, 1891- To all whom it may concern:

Be it known that I, JOHN V. OARVELL, a citizen of the United States, residing at Eddyville, in the county of Pope and State of Illinois, have invented certain new and useful Improvements in KeyholeGuards 'for Pad locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in keyhole-guards; and it consists in providing the lock-casing proper with an attachment whereby the keyhole of a lock may be concealed from view, as will be more fully hereinafter described, and specifically set out in the claim.

The objects of the invention are, first, to so conceal the keyhole that the uninitiated cannot obtain access thereto to pick the lock, and, second, to prevent the water from getting int-o the interior of the lock and injuringthe working parts of the same. These objects are attained by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents a perspective view of a padlock with my improved attachments applied thereto, showing the keyhole concealed from view Fig. 2, a similar view showing the door open and the keyhole exposed to view; Fig. 3, a side elevation having a portion of the casing broken away to show the pivoted latch and its spring.

In the drawings, the letter A indicates the side plates of the lock-casing proper, B the bottom or end plate the side edges of which extend slightly beyond the face of the side plates, and C the keyhole. Extending across each side plate, near the top thereof, is athin rib or wall D. Between the one on the front side of the lock and the side extension of the bottom plate B at one side is hinged a door E, provided with a hook or catch 6. Located at the end opposite to that where the door is hinged and between the side plates, which are Serial No. 407,965. (No model.)

extended for the purpose, is a pivoted latch F, held normally in looking position by a springf. The face-plate at one corner is cut away to receive the catch or hook e and allow it to engage the pivoted latch. The opposite or back side of the lock is finished to resemble the front. A supplemental casing or plate G, similar in shape to the door E, is rigidly secured between the rib or wall and the extension of the bottom plate.-

Between the side plates at the end opposite to that in which the latch F is pivoted is rigidly fitted a plate (not shown) to resemble in appearance the outside of said latch, so that when the hinged door is closed the two ends, as well as the two sides, will present the same general appearance.

By applying pressure to the upper end of the spring-latch thehook or catch on the door will be released and the latter can then be readily opened. The door and plate G form a supplemental side casing, which, besides protecting the keyhole to prevent the look from being tampered with, serves to prevent the water from entering the interior of the lock and damaging the working parts.

The device is simple and inexpensive in construction and may be applied to almost any lock now in use, but is preferably made with the lock.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with the lock casing proper, of the extended bottom plate, the ribs JOHN V. CARVELL. Witnesses:
